The "apse," as befitting its significance, contains a monumental projection of the scans-enlarged views of the map-landscape's verso, its invisible back side-a projection which generates an illusion of space despite its being flat and impenetrable whether by the sight lines or by the viewer.

In this projected space of visual collapse, interior becomes exterior (surface), blurring the differences between near and distant, real and imaginary, three-dimensional and two-dimensional.
